- Cat6 tighter twist allows full duplex (two-way communication) which Cat5 does not.
- Cat6 materials and pair geometry are slightly larger than Cat5 including jacket thickness.
- Cat6 has higher bandwidth performance (250 MHz) vs Cat5 (100MHz).
- Cat6 has lower attenuation, crosstalk and return loss.
- Cat6 provides a higher signal to noise ratio yielding higher reliability.
